Types of crushers

Heavy artificial sand is a granular material obtained by crushing hard rock minerals — limestones, granites, pumice, marbles, etc., as well as all kinds of slags. The grain of such a material turns rough, with a complex uneven surface, which improves the strength of the solution. The sands obtained in this way are used as aggregates in building mixes, plasters, if strength and a special relief of the outer layer are necessary. The size of the grains is allowed to vary, it varies from the purpose of the solution and is often considered equal to the size of natural sands.

Main types of industrial crushers

The main types of crushers include jaw crushers, cone crushers.In the cheek grinding is carried out by crushing and abrasion.

There are also roller crushers and impact crushers (hammer and rotary). Also, sometimes runners are referred to as grinding machines, but it is more correct to consider them as crushers. The process of destruction includes crushing and abrasion.

Runners and mills are used for crushing. There are drum mills (ball mills, pipe mills).

The Department of Metal Technology of MGSU has developed a new promising steel for casting jaw crushers. The existing 110G13L grade steel has been upgraded, which makes it possible to save about 20% on metal loss during crushing. This is the 110G13X2TL brand, which improves the energy saving of crushers.

Spring Cone Crusher

In these crushers, crushing with bending occurs.

In such a mechanism, the motor rotates around a rigidly fixed axis with a pulley in such a way that the crushing cone then approaches, then moves away from the fixed crushing wall.

The advantages of cone crushers include a large crushing force, low costs, high productivity, the possibility of using for obtaining material of different grain sizes.

Bowl bearings and crushing cones are subject to increased wear in this design.

Jaw Crushers

The destruction process in this machine is carried out by crushing and abrasion.

The principle of operation of the mechanism is based on the compression of the rock by the steel cheeks of the material, which leads to huge compression and shear stresses that grind stones into sand. One of the working surfaces of the crusher is fixed. The second is attached to a connecting rod that creates swinging movements of the cheek. The connecting rod shaft rotates by means of a V-belt transmission from a diesel or electric motor.

SDM-109

In modern complex rolling cheek crushers, higher shear stresses are produced. Vibro-jaw crushers are also used for high-strength rocks.

Rotary Crushers

In a rotary crushing machine, stones are crushed by rotating the rotor with hammers mounted on it by hitting pieces on the chipping grates.

As mentioned above, the most worn elements of these mechanisms are directly interacting with the rock – cheeks and crushing cones.

Purchase of spare parts for crushers

To purchase replacement parts, the Prevouralskaya company "Development Industry" offers a wide range of spare parts for jaw, rotary, cone crushers.

Here in the foundry castings are made of high-manganese steel 110G13L and gray cast iron SCH-20.

Various products are produced for jaw crushers: mobile and fixed crushing plates, spacer plates, etc., for rotary crushers: beams, clamps, beaters, cones and other details of cone crushers are also in demand.

LLC "Development Industry" offers customers a flexible system of discounts.
